Application filed September 11, 1906. Serial No. 834,181.

To all whom it may concern:

Be it known that I, FREDERICK J. Harmon, a citizen of the United States,residing at Savannah, 'in the county of Qhatlutm and State of Georgia,have invented new and useful Improvements in Gan-'lapping Apparatus, ofwhich the following is a specification.

This invention relates to what I shall for convenience term can tappingapparatus. This title as stated is adopted merely for convenience asreceptacles of kinds other than those known specifically as cans can besuccessiully brought under the action oi the apparmus. The latter issimple in construction and effective in action, in that-it assures thesolid and uniform packing oi pulverulent substances of different kindsin cans.

An apparatus embodying the invention may be advantageously employed inmany ways, for example, in combination with a weighing machine such asthat shown in Letters-Patent numbered 791,342 granted to me May 30,1905, and to which reference may be had. When the can tapping apparatusis employed with such a weighing machine the latter automatically weighsout and delivers charges of material to cans, which charges are packedas hereinbeiore brought out in the respective cans.

In. the drawings accompanying and forming part of this specification Ishow in detail certain forms of embodiment of the invention which toenable those skilled in the art to practice said invention will be iuilyset forth in the following (inscription, while the novelty of theinvention will be included in the claims succeeding said description.

Referring to said drawings, Figure l is a sectional side elevation of anapparatus embodying the invention. Fig. 3 is a view corresponding toFig. l, of a modified form oi apparatus. Fig. 4 is a sectional iront andFig. 5 a sectional side elevation of the parts shown in Fig. 3.

Like characters refer to like parts throughout the sovcral figures.

1 will first describe the construction represented in Figs. 1 and 2 andafterwards that shown in Figs. 3 to 5. Referring now particularly to thefirst mentioned two figures, the numeral 2 denotes a frame memberrepresented as horizontally disposcdnnd which may be oi wood, metal or acomposition of these materials. This irame member constitutes a part oithe iramowork oi the apparatus which iramcwork is denoted in a generalway by 3. lhave only sh or: u part of the framework of the machine iorthis is all that is necessary to a iull understanding oi the invention.From the iramework 3 (see Fig. 1) there is shown as extending a bracket4 which constitutes a support l' or the shalt 5, said shaft 5 being inpractice rotated in any suitable way, for example, by means of sprocketgearing denoted in a general way by 6.

This shaft 5 has fastened to it in any desirable Way a toothed member 7which is represented as consisting of .a mutilated ratchet wheel, theteeth of which extend a, little less than half the distance around theperimeter thereof; this, however, is not essential, nor is it necessaryto employ a ratchet wheel, for as will hereinafter appear I may employ amember for performing the functions that the part 7 does which is notstrictly speaking, a. ratchet wheel, but is, however, a toothed member.I I The bracket 4 in addition to constituting a support for the shalt 5sustains a second shait as 8, the latter being in. the present case oirocking type and being represented as located above and at one side ofthe shaft 5. There is fastened to this shaft 8 in somcsuitable way anarm as 9 to which between the ends thereof is connected one end oi aspring as 10, the other end of said spring being connected with thebracket 4 at a point substantially remote from the arm 9. This spring 10acts upon the arm 9 in opposition to the mutilated ratchet wheel 7. Whenthe teeth oi the ratchet wheel 7 are brought opposite the projection 11at the free end oi the arm 9 0n the rotation oi the said ratchet wheel 7the spring 10 will draw said projection 11 into the spaces between theteeth oi said ratchet wheel and the angular portions of the teeth willmove the arm contrary to the spring l0, the result being that when thearm 9 is in the range oi action of the teeth of said wheel 7, said arm 9will be vibrated or oscillated. The shaft 8 fixedly carries a second armas 12, said arm 12 being represented as provided with a circular ordisk-like head 13 (see Fig. 2). From this head 13 at or near the centerthereof there riscs a shank or stem 14 terminating at its upper end in ahead 15 which on the working stroke of the arm engages centrally a canas 16 shown by dotted lines in Fig. 1. The arm 12 with the headed shankor stem 14 constitutes a tapping member, while there is coijperativowith said tapping member a second tapping member as 17. The head 15 actsdirectly and centrally upon the can While the tapping member l7transfers the force oi the head 13 to the can margin-ally oi the latter.The two tapping members, there- .ioi'c, cooperate to thoroughly andevenly pack the contents of the can and to secure the best possibleresults the tapping member 17 is loosely mounted so as to impart a quickblow to the can.

"llio tapping member 17 is represented as being of annular form; by this1 do not mean that it is necessarily circular, but rather that it istubular in order that the headed shank 14 may work th crethrough. At theupper end of the tapping member 17 is a flange 18 which is that part ofthe tapping member 17 which on gages the can. This flange is representedas resting upon several pins 19 extending from the wall of an opening21520 formed in the frame member 2. The pins 17 or the flanged portion18 thereof is in the same hori- Zontal plane as the horizontal flangesof the parallel L-shaped strips 2i, which L-shaped strips eoaet to produce a way for the can 16 which is advanced niong said way in somesuitable manner as by a slat l8 onstituting part of can advancingmeehanisnu not shown. lndotted lines in Fig. 1 have represented at l9 ahopper which delivers the charge of material into the can 16 locatedbelow said hopper and while said can is resting on the tapping member17. When a can as l1; is upon the tapping member 17 as shown in Fig. land when the arm 12 is in motion as hereinb'el'ore set forth,

the head 15 will lirst of all be brought centrally against the underside of the. eanbottt'un so as to propel the material in the centralpart of the an rapidly upward, such material subsequently settling in a.dense condition. After the head 15 strike the can the head 13 strikesthe lower edge of the tapping member 17 so that the flanged upper end ofsaid tapping member 17 will engage the marginal part ol the can in orderto upwardly elevate the material'in the can around the central partthereof such outer material afterwards settling in a dense condition.These operatitms are repeated in close order during the vibration of thearm 9 in order to effectually pack the material in titer-an.

The iorm of invention shown in Figs. 3 to 5 is of advantage and will nowbe set forth. The framework shown in these figures is denoted in ageneral way by 25 and comprises a frame member or transversely disposedbeam as 26 in connection with which the tapping mechanism directlycooperates. the can 27 being sustained by said frame member or beanriltiwhile its contents are being densified. in said Fig. 3 and in Fig. 4 areshown strips 28 and a slat 29 which perform the same functions as thestrips 2 band slat 1S herciribeforc described. The hopper for doliveringa charge of material to the can 27 is denoted by 30. The can 27 is movedonto the frame member or'beam 26 by conveying mechanism of which theslat 29 forms a part.

To the right of and below the frame member 26 and supported tor rockingmotion by the frame work 25 is a rock-shaft 31. Afiixed to and dependingfrom the rock-shaft 31 is an arm 32 to the lower end of which isfastened one extremity of a spring as 33, the opposite end of saidspring being connected with the framework 25, this spring serving toimpart a working stroke to a tapping member hereinafter described, thereturn stroke of said tapping member being effected by a toothed memberas 34, as will hereinafter appear. This toothed member 34 may beoperated like the wheel 7 hereinbefore described, that is, bysprocketgearing. The shaft 31 is provided with a longitudinally curvedarm 35 constituting a tapping member and with a third arm 36 havingfastened to its free end one branch of a resilient U-shaped member 3-7,the other, branch of said member 37 being ongageable by the teeth of thetoothed member 34. The spring 33 as indicated imparts a working stroketo the tapping member iifi, the return movement of said tapping memberbeing'offected by thoteeth oi the member 34 striking against the Ushapedmember 37. Therefore, when the arm 36 is being opl l l t l l l t ltapping member 35, however, does not directly engage the can 27 butoperates on the same through the intervention of two tapping members 38and 39. The tapping member 38 consists of an elongated shank having a.head -10 at its upper end which engages the under side of 'the can 27substantially centrally thereof. 1 be two tapping members 38 and 39operate vertically in an opening in the beam or frame member 26, whichlatter during the tapping operation sustains the can 27. The outertapping member 39 is of tubular form, theliead 40 of the inner tappingmember beingmouable in tlie hollow head of the outer or tubular tappingmember. f-The tapping member 38 has a'pin 41 to enter'a slot in the bodyof the tapping member 39, while a pin 21342 on the frame member 26enters a peripheralgrom'e in the body of said tapping member 39, the twopins preventing the two tapping members 38 and 39 frombeingaccideiitally moved irom place. The tapping nmember'39 seatsagainst a ring as 43 of rubber or other suitable eushio extends slitapping member 39 and t; member 39 beam or frame member 26.

be lower end of the tapping In addition to this the up extends below theunder surface of the per surfaces of the tapping member 38, tappingmember 39 and frame member 26 are arranged in superpos e planes asindicated clearly in Fig. 5 by virtue of which a succession of blows canbe imparted to the can resting" on said frame member 26. First of allthe tapping member {55 will thrust the tapping member 38 1'oward; thetapping member 39 will then be engitged by the tapping member 35 andfinally the frame member 26 will be engaged by said tapping member 35 togive the can three distinct andrapid blows.

It will be apparent from what I have previously l statod'that the cantapping mechanism has a plurality of tapping members, the workingportion of one of whi ch surrounds the Wgrlring portion of another. Byvirtue of tapping members related as thus set forth one tapping membertially central portion of the bottomoi the can, while another operatesagainst the marginal portion of saidcan, and those working portions arepreferably, though not necessarily, flattened so as to secure a widearea of effectiveness.
